Only problem is, that's about as generic an icon as you could get by mixing Apple's default iOS icon style with a standard WiFi and Sync icon. Not that unique...
I'm pretty sure that wasn't the "standard" WiFi icon until it showed up in OS X. I think the original "standard" WiFi icon was either this one or the one that looks like a person with radio waves coming out of their head: http://en.wikipedia.org/wiki/File:Wifi_logo.jpg
There was no international standard wireless Internet logo for a long, long time. There still may not be. But this one is indeed Apple’s standard AirPort icon (they dropped one ring going OS X → iOS due to size contraints).
